Title: Protective agents against textile pests, mould and bacteria
IPC: C07C311/37
Filed: 1958-06-09
Abstract: Haloalkyl-, haloaralkyl- and-or haloarylsulphonamides of aminodiphenylamines or Niminosubstituted aminodiphenylamines, halogenated in one or both of the aromatic nuclei, are obtained by reacting the corresponding aminodiphenylamines, which may be substituted, with haloalkyl-, haloaralkyl- or haloarylsulphonic acid chlorides.  Alternatively the halogen may be introduced in other ways, e.g. by chlorination or bromination with free halogens or sulphuryl chloride or bromide, by the reaction of diazonium chlorides to give fluorine or chlorine compounds, or by the exchange of moveable groups for fluorine.  In an example, 2-aminodiphenylamine is dissolved in anhydrous pyridine and chloromethane-sulphonic acid added dropwise while stirring and cooling in a mixture of ice and salt.  After stirring for several hours, the mixture is poured into water, the separated reaction product is dissolved in water with the aid of sodium hydroxide, treated with carbon and fuller's earth, filtered, reprecipitated with acid, filtered off, washed with water and dissolved in ether. This solution is filtered through carbon and distilled, and the residue recrystallised from aqueous methanol.  The resulting chloromethanesulphonyl-2-aminodiphenyl-amine is dissolved in orthodichlorbenzene, a little ferric chloride added, and chlorine introduced until analysis shows approx. six atoms of chlorine per molecule.  The solvent is then distilled off and the residue worked up as above.  Numerous examples are given in the specification of starting materials for and products obtained by the above condensation, with or without the after-chlorination. Specification 738,758 is referred to.

Title: Improvements in or relating to cathode ray counter tubes
Inventor: KRAUSE ANTHONY VICTOR DE VERE
IPC: H01J31/04
Filed: 1955-06-30
Abstract: 823,528. Cathode-ray tubes. RANK CINTEL Ltd. July 2, 1956 [June 30, 1955], No. 18919/55. Class 39(1). A counting tube for moving a beam around ten stabilized positions arranged in a circle on fluorescent screen 22, Fig. 1, by means of cyclic switching voltages all of the same amplitude, has two composite stabilizing electrodes 20, 21, Fig. 1, back coupled to orthogonal pairs of deflecting plates 14A, 14B, 15CD, Fig. 2. Electrode 21 as shown in Fig. 4, consists of two sets of plates 26, 28 and 27, 29 each defining a semi-annular space in which the beam is constrained to remain by the usual backcoupling to vertical plates 15CD ; plates 26, 27 and 28, 29 are cross-connected. Semicirculae 30 ensures that on switching on the beam rises to position O. Electrode 20 as shown in Fig. 3, consists of two similar toothed rings 24, 25 back-coupled to horizontal plates 14A, 14B. It is explained that when a cyclic switching voltage is applied to plate 14A the negativegoing excursions move the beam successively to stable positions 1, 2 on the right hand edges of teeth 33, 34. The next excursion moves it to X. After this it is the positive-going excursions which move the beam through positions 3, 4, 5, 6, 7 and the negative ones which return the beam via 8, 9 to 0. Teeth 35, 36, 37, 38, 42, 43, 32 are narrower than the beam diameter, as are also spaces 1, 0, 6 and 7. Resistors 16, 17, 18, 19 in the feedback circuits are preferably within the tube envelope.

Filed: 1975-05-06
Abstract: 1489794 Projectile fuze L STOCKMAN and S STOCKMAN 6 May 1975 [6 May 1974 23 April 1975] 18957/75 Heading F3A A fuze for a rifle grenade comprises a striker 134 and a detonator 103 carried by a rotor 105, the detonator being brought automatically into alignment with the striker some time after firing the projectile only through the action of a force directed along the axis of the projectile and arising out of the slowing down of the projectile (but not the rotor) owing to the resistance of the air. The rotor has an eccentric centre of gravity and pivots about pins 106 that are engaged in longitudinal slots 107 in a member 130, the slots being closed by an annular member 108 which is subject to the pressure of a spring washer 109. The striker is secured in a locking position for the rotor by means of balls 125 and inertia elements 115 and 141. Upon firing the grenade, the inertia element 115 sets back and is followed by the inertia element 141 which simultaneously urges the balls 125 into the interior of the striker. As the axial acceleration of the grenade subsides, a spring 116 thrusts the inertia element 115 forwards and the element engages a stop 135 thereby causing the striker to move forwards and be withdrawn from a locking bore 112 in the rotor. Meanwhile, the rotor, which is no longer subject to axial acceleration forces, lifts slightly from a surface 110 and is free to rotate about its pivot pins as the grenade slows down. Loss of the striker as it moves forwards under the influence of the inertia element 115 is prevented by engagement of a frustoconical surface of the striker in a cylindrical bore 142 of the fuze housing.

Abstract: 317,316. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Briggs, L. A.). Aug. 13, 1928, [Convention date]. Transmitting systems for code telegraphy.- Signalling is effected simultaneously on a plurality of channels, and the spacing time of one channel is used as the marking time of another channel. A cable-Morse-code tape transmitter 1 controls marking relays 7, 8 which cause a wireless transmitter 16 to emit different frequencies by shortcircuiting portions of a tuning coil 15. Similarly, another tape transmitter 2 controls relays 9, 10 to produce two other frequencies. The tape transmitters are driven by a common motor M through gearing 21, 22 so arranged that the marking impulses of the transmitter 2 occur during the spacing intervals of the transmitter 1 and vice versa. When both tape transmitters are spacing a frequency corresponding to the whole of the coil 15 is transmitted. More channels may be provided by increasing the number of frequencies, with appropriate slowing of the signalling in the individual channels. At the receiving station a separate receiver for each frequency is used, or, if one receiver is sufficiently broadly tuned to receive more than one frequency, filter circuits are employed.

Title: A valve assembly for breathing apparatus
Inventor: BLOOM AARON
IPC: A62B9/04
Filed: 1960-05-30
Abstract: 940,581. Respiratory appliances. SIERRA ENGINEERING CO. May 30, 1960, No. 19042/60. Heading A5T. A valve assembly for breathing apparatus having a fixed main oxygen supply in an airplane and an auxiliary supply carried by the pilot, the main supply connection being closed automatically on severance from the main supply when the pilot leaves the plane leaving only the auxiliary supply operative, comprises a hollow body having a main supply inlet connected to one end, a valve in the inlet which is spring urged to close the inlet, an auxiliary supply inlet communicating with the hollow body at a point removed from the main supply inlet and a second spring normally urging an auxiliary valve to close the inlet but allowing the valve to open when the main supply valve is closed. As shown, a body 14 on which a master hose is mounted at one end 25 has screwed into the opposite end a main supply inlet 42 which receives a hose (not shown) connected to a fixed main supply of oxygen. A valve element 54 carrying a stem 51 bears against a seat 55 in its closed position. A guide 50 mounted on the stem is slidable in grooves 49 in the inlet 42 and acts as a stop for a spring 65 the other end of which abuts against a shoulder 66 adjacent the valve seat 55. A relief valve element 57 is normally urged by a spring 58 weaker than the spring 65 into a position covering apertures 56 in the valve element 54. A hose (not shown) from a portable auxiliary oxygen supply is connected to an auxiliary supply inlet 29 which is screwed into a connection 26 on the body 14 and comprises a valve seat 31 against which a valve element 32 is urged by a spring 33. During operation with either gas supply the expired gases are exhaled through an exhaust valve (not shown) on the mask. Mounting the fixed supply hose on the member 42 moves the guide 50 into recesses in a retaining ring 47 and the valve element 54 into the open position. On removal of the supply hose the valve element 54 closes under the action of the spring 65. The portable supply hose is already connected to the inlet 29 and since the pressure on the body 14 fell on closure of the main valve gas pressure in the hose unseats the valve element 32. If pressure in the body now becomes excessive, the relief valve element 57 opens. When the pilot reaches a lower altitude, the ambient pressure may overcome the main valve spring 65 and ambient air be mixed with the oxygen in the body 14.
